The blade holder members l1 and la 'are preperly aligned with each otherand with the blade. f by means of a pair of spaced `pins and 5I vaslshown in Figs. 3 vand 6 on the outer holder member I8, such vpinspassing through apertures like 1 arides.mirri-rl einer;

52 and 53 respectively in the blade 4 and through apertures like 54 asshown in Fig. 6 in the inner blade holder member I1. The pins 50 and 5|also pass through apertures like 55 in the guard 2 in order to locateblade holder 3 and the cutting edges 20 and 2| ofthe blade with respectto the guards 5 and. vv Guard v5f. is fused for trimming, whereas guardG is used for thinning. As shown in Figs. 3 and 4, all of the members inthe guard 5 have long slots 60 having inner ends which are crossed orintersected by the cutting edge of the blade. On the other hand, thealternate slots like 6I in the other guard 6 are comparatively short andare not'intersected by the cutting edge 2l where--- by, when thinningthe hair, whatever hair falls into the short slots 6| is not cut bytheblade.

When using the device for shaving, thejnut ,G5 1

is operated to elevate the'blade l to the position shown in Fig. 5withthe cutting edges oithe blade a" slight distance 'above the contoursI l and l'2g'of the guard. When the device is used for trimming thehair, the hair remaining'onthe skinafter cutting is shortenthe more theblade dis elevated with respect vto the guard 2. .A short Yhaircut isobtained when theblade is near the tips I3 and I4, while a long haircutis obtained if. the blade is in its lowermost position. The length ofhaircut can be varied by adjusting the blade with respect to the guardtips I3 and lll. 'Ifhe cuttingscan be blown from the device lby moving,the blade holder 3 to an .elevated positionV beyond that shown in Figg,this being accomplished by operating thenut 45. l

Ihe--shortouter tubular member and the innertubular extension 48 serveas a handle for the device. l f

It will be apparent that'various modiiications may be made in theinvention without .departing from the spiritof the following claimsVIrclaim: `.1.:.1A hair trimming type razor, comprising curved companionrazor blade holders for. clampin'gnav double edge razor blade in curvedposition,
